CONTENT
	1. allCWS_replication.csv: 
		Replication data for analyses using community water system sampling data (results presented 		in Table 3 and Figure 1).
		
	2. HUC_replication.geojson: 
		Replication data for analyses using drinking water data in 8-digit hydrologic unit code (HUC)
		watershed boundaries (results presented in Table 2). Note that the projection of this spatial
		dataset may need to be changed manually to be recognized as Universal Transverse
		Mercator depending on your program's defaults.
